With out looking for a professional clothing alteration shop, here are some steps to change the zip of a jacket:
Measure the length of the existing zip: Measure the length of the existing zip using a tape measure. This will help you to purchase a replacement zip that is the same length.
Purchase a new zip: Purchase a new zip that matches the length and style of the existing zip. Make sure that the new zip is the correct size for the jacket.
Remove the old zip: Use a seam ripper to carefully remove the stitches that hold the old zip in place. Be sure to remove all of the stitches so that the zip can be fully removed from the jacket.
Prepare the new zip: Unzip the new zip and place it face down on a flat surface. Pin the two sides of the zip tape to the jacket, making sure that the teeth of the zip are aligned with the jacket’s front edges. Pin the top and bottom of the zip tape in place as well.
Sew the new zip in place: Use a sewing machine or hand-sewing techniques to sew the new zip in place. Begin at the bottom of the jacket and sew up one side of the zip, stopping at the top. Repeat on the other side of the zip. Make sure to sew close to the teeth of the zip for a neat finish.
Finish the top of the zip: Use a hand-sewing needle and thread to secure the top of the zip in place. Fold the fabric over the top of the zip and sew in place, making sure that the stitching is hidden inside the jacket.
Check the zip: Once the new zip is in place, zip and unzip it a few times to make sure that it is working smoothly.
With these steps, you should be able to successfully change the zip of a jacket. However, if you are not confident in your sewing skills, it may be best to seek the help of a professional tailor or seamstress.
